When you make ice cubes, the entropy of water

Options

A. does not change
B. increases
C. decreases
D. may either increase or decrease depending on the process used.

Explanation

To solve the question regarding the change in entropy when making ice cubes from water, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Entropy**:
- Entropy is a measure of the disorder or randomness in a system. Higher entropy indicates a more disordered state, while lower entropy indicates a more ordered state.

2. **State of Water and Ice**:
- In the liquid state (water), the molecules are in constant motion and are less ordered, which corresponds to a higher entropy.
- In the solid state (ice), the molecules are arranged in a fixed structure, leading to a more ordered state and thus lower entropy.

3. **Phase Change from Water to Ice**:
- When water freezes to form ice, the molecules lose energy (heat) and arrange themselves into a structured lattice. This transition from a liquid to a solid results in a decrease in disorder.

4. **Conclusion on Entropy Change**:
- Since the transition from water (liquid) to ice (solid) results in a more ordered arrangement of molecules, the entropy of the system decreases.

5. **Final Answer**:
- Therefore, when you make ice cubes, the entropy of water decreases.
